NASA / ESA’s Hubble Space Telescope captured the closest ever image of a quasar. Classified as 3C 273, it’s located roughly 2.5 billion light-years from Earth, with a luminosity over 10 times brighter than the brightest giant elliptical galaxies.
Hubble’s observation revealed that the environment surrounding quasars is far more complex than first suspected. More specifically, this area appears to be where galactic collisions and mergers between quasars as well as companion galaxies took place, thus reigniting the theory that giant black holes drive quasars.

With the fine spatial structures and jet motion, Hubble bridged a gap between the small-scale radio interferometry and large-scale optical imaging observations, and thus we can take an observational step towards a more complete understanding of quasar host morphology. Our previous view was very limited, but Hubble is allowing us to understand the complicated quasar morphology and galactic interactions in detail. In the future, looking further at 3C 273 in infrared light with the James Webb Space Telescope might give us more clues,” said Bin Ren, Researcher from the Côte d’Azur Observatory and Université Côte d’Azur in Nice, France.
